The North Face Women’s Super Diez Vest is really super. It was supposed to be called the Women’s supercalifragilisticexpialidocious Diez vest, but that name was too long. Now the name is just as compact as this vest. But don’t be fooled by the slim and sleek appearance of the Super Diez Vest; it’s actually ridiculously warm. The lightweight down insulation and Pertex nylon exterior provide durable, ripstop warmth without the bulk.
